Carbide Inner Cooling Twist Drill is a kind of hole processing tool. Its characteristics are from the shank to the cutting edge. There are two spiral holes that rotate according to the twist drill lead. During the cutting process, compressed air, oil or cutting fluid penetrates to achieve The function of cooling the tool can wash away the chips, reduce the cutting temperature of the tool, and increase the service life of the tool. In addition, the TIALN coating on the surface of the drill bit with internal cooling coating increases the durability of the drill bit and the stability of the processing size.
Therefore, the internal cooling Drills have better cutting performance than ordinary carbide drills, and are especially suitable for deep hole processing and difficult-to-machine materials. Drills with internal cooling holes are used to reduce the impact on the drill and product appearance caused by high heat during high-speed processing of the drill.
The drill bit with double cold holes effectively solves this problem and brings you high-speed and efficient drilling; internal cold drill maintenance
1. When drilling steel parts, please ensure sufficient cooling and use Metal cutting fluid.
2. Good drill pipe rigidity and guide rail clearance can improve the accuracy of drilling and the life of the drill;
3. Please ensure that the magnetic base and the work piece are level and clean.
4. When drilling thin plates, reinforce the work piece. When drilling large work pieces, please ensure that the work piece is stable.
5. At the beginning and end of drilling, the feed rate should be reduced by 1/3. For powdery materials, such as cast iron, cast copper, etc.,
6.you can use compressed air to help remove chips without using coolant.
7. Please remove the iron chips wound on the drill body in time to ensure smooth chip removal.
The Carbide Inner Cooling Twist Drill bit has two spiral holes that rotate according to the twist drill lead from the shank to the cutting edge. In the cutting process, compressed air, oil or cutting fluid can be used to pass through the two spiral holes for cooling The function of the drill bit can wash away the chips, reduce the cutting temperature of the tool, and increase the service life of the tool. The internal cooling drill usually adopts the surface TIALN coating, which increases the durability of the drill and the stability of the processing size.
Therefore, the internal cooling drill is more than Ordinary carbide drills have excellent cutting performance, and are especially suitable for deep hole processing and difficult-to-machine materials. Drills with internal cooling holes are used to reduce the damage to the drill and product appearance caused by the high heat during high-speed processing of the drill. , The cutting efficiency of the internal cooling drill bit is 2-3 times that of the ordinary alloy drill, which is the best choice for high-speed and high-efficiency drilling of modern machining centers. But most people do not understand the cemented carbide rod material used in the internal cooling drill.
